How about a radio calibration tutorial? .. Ive spent an hour on this and I cant get my Futaba 6exa working right. The slightest touch of any controll max's out the jittry calibration bar. Have reset the radio to factory defaults. All trims set to +/- 0. Not sure what PPM mode is, but the manual here has no relevance regarding it (hit cntrl+f to search pdf contents) http://www.futaba-rc.com/manuals/6exa-manual-v1_1.pdf
Dont know what else to do. Cant get AFPD settings zero'd out. /sigh
